Seat Position Sensor: Description and Operation

STPS (SEAT TRACK POSITION SENSOR)

The STPS operated via a non-contacting magnetic proximity sensing device combined with a simple electronic circuit resulting in the ability of producing two separate & distinct logic level signals.




The STPS output signal is altered by the proximity of a separate ferro-magnetic shunt, which is linked via the seat track. The logic signal produced is the result of the proximity device being activated (no shunt present) or deactivated (shunt present).
